Try the following:
# vi /etc/vinum.conf
drive a device /dev/ad0s1e
drive b device /dev/ad2s1f
volume mirror setupstate
plex org concat
sd length 0 drive a
plex org concat
sd length 0 drive b
# vinum
vinum -> resetconfig
vinum -> create -v /etc/vinum.conf
vinum -> quit
The key points are:
1) use ad2s1f instead of ad2f since the disk has a true partition entry
2) specify length as 0, i.e. auto size.
This is basically what I do and is covered in the vinum(8) man page.
